sown-DASH BLANK.

To all whom it may concern;

Be it known that I, HENRY J. HINDE, a citizenof the United States, residing at T- ledo, in thecounty of Lucas'andState of Ohio, .have invented anew and useful Cowl- Dash Blank, of which the following, is a specification.

The device forming the subject matter of this application is a cowl-dash blank and the invention aims to provide, as an, article of manufacture, a cowl-dash blank embodying a removable portion of novel form adapted to act as a reinforcement during the shaping of the cowl-dash.

With the foregoing-and other objects in View which will appear as the description proceeds, the invention resides. in the combination and arrangement of parts and in the" details of construction hereinafter described" and claimed, it being understood that; in the preciseembodiment of thechanges -invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention. In the'drawings accompanying thls s'pec1- I fication and forming a part thereof, the pre- 1 cowl dash being of that type which 'is formed singly and the bottom forming element or portion discarded. Fig.3 is a bottom plan view of the cowl dash during the same stage of formation. Fig. -4 is across sectional view taken on the line 4+4 of Fig.

cross sectional view of a 3. Fig. 5 is a are bestamping in which two cowl'dashes ing simultaneously produced. representing the same prior to the final cutting and trimiming steps. Referrlng to the drawings in which si'm1- lar reference numerals designate correspond ing parts throughout the several views, the

I finished cowl as illustrated in Fig. l includes the side walls 4, top 5 and inwardly extending frontal flange or rim F. The bottom is entirely open as illustrated at 9, as is the usual construction of cowl dashes.

It has been the usual practice heretofore Specification of Letters Patent. I I Patented B1 '7, 1916, Application filed May 5, 1914. Serial No. 836,511. v I I in forming bottomless cowl dashes with open fronts, to construct the same of a plurality of sectlons brazed, welded or riveted together. e I

The present invention contemplates a process by meansof which a cowl dash may be formed from a single piece of sheet metal without danger or likelihood ofdistortion during the: several steps ofdrawing and stamping and'with the finished article embodying a unitary structure and possessing all-the advantages thereof. vWith ,this in View, a blank 1s first cut and includes a portion such that the cowl dashafter being subjected to the shaping or drawing operations will include the full front wall 9 and bottom 6. This -provides that the blank may be clamped upon all sides for the successful shaping and drawing operations. 'The full front wall 9 and bottom '6 provides that the cowl dash dunng its intermediate stages of formation as illustrated in Figs. 2, 3 and 4 will be in the form of an open ended receptacle, thus providing a rigid structure and preventmg its distortion when the final stamp. ing and cutting operation is performed.

After the blank has been stamped in the form illustrated in Figs. 2, 3 and 4, it is placed in suitable dies and the bottom 6 removed and thefront wall out along the dot- I ted line 12 to form the frontal flange F.

The dotted line in Fig. 2"corresponds to the hue 12 In Fig. 1 which in that figuredefines the inner limit of the said frontal flange. A rib 11 is formed in the frontal flange which I braces the same and also provides. a projection .upon which the hood or bonnet of a vehicle may rest. 1

The blank 5 represents an intermediate step inthe process of simultaneously forming two complete cowl dashes. I The blank used in this case is sufliciently large to form two complete cowl dashes, the lower cowl dash taking-,thepla'ce and performing the functions of the bottom 6. The blank is interposed between suita le dies and by successively drawing is' shaped as illustrated in Fig. 5. The cowl dash is then interposed between suitable dies and .cut along the line 14, and at the same time the front wall 9' is removed.

-The finished article as illustrated in Fig. 1, includes the rearwardly projecting extensions 7 which conform to and are adapted tion of the front being removable to form a to engage a vehicle body. The side Walls 4 frontal flange. and top 5 may be also curved so as to har- 2.
